y HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 637,807, dated November 28, 1899.

Application led November 16, 1896. Serial No. 612,251. (No model.)

To all whom, it 71mg concern,.-

Be it known that I, JAMES MAOPHAIL, a citizen of the United States, residing at Blue Island, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Hay-Rakes, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 is a plan View showing a hay-rake constructed according to myinvention. Fig. 2 is a vertical longitudinal section on the line 2 2 of Fig. l. section on the line 3 3 of Fig. l. Fig. 4 is a rear elevation of the clamping-plate shown in Fig. 3, taken on the line 4 4 thereof. Fig. 5 is a vertical section on the line 5 5 of Fig. l.

My invention relates to hay-rakes, and has for its object to provide improved mechanism forcleaning or stripping therake-teeth.

Referring to the drawings by letter, A represents the thills or shafts, A the main framebar, and B a transverse angle-iron bar, all of which parts go to make up the frame of the machine in the usual manner.

To the angle-iron bar B are secured the rearwardly-extending brackets B', provided with bearings Z9, in which is mounted the wheel-shaft C. The said wheel-shaft is provided near its center with the ratchet-.wheel C' and at opposite ends with the carryingwheels D, mounted on sleeves D', keyed to the shaft C.

. To the rake-teeth angle-iron bar E are secured two or more forwardly-extending brackets E', which are loosely mounted at their forward ends upon the shaft C. To the upright flange of the angle-iron E are secured the rake-teeth F in any desirable manner. The attachment which I prefer will be illustrated in respect to the strippers. Beneath the said angle-iron E there is pivotally mounted a pawl G, adapted to be normally held out of engagement with the ratchet C by the expansion-spring G. To the pawl G is secured a link and chain G2, connecting it with the foot-lever G3. When the foot-lever is depressed, the pawl G is thrown into engagement with the ratchet-wheel C and the rake is elevated in the usual manner.

Fig. 3 is an enlarged verticalv Upon the top of the angle-iron E is rigidly mounted a lever H, to which is pivoted, as at h, a spring-controlled dog H', adapted to engage with the teeth of the segmental rack H2, also pivoted to the lever H, as at h. A connecting-rod I is pivotally secured to the racksegment H2 and the short arm I of the hand lever I2. The hand-lever is adapted to hold the rake in its raised position when it has been elevated by the ratchet C and the pawl G. An adjustment of the dog H on the rack H2 will control the position of the rake-teeth in their normal lower position.

Referring now more particularly to the strippers, I show live strippers J, each consisting of a straight rod of elastic metal J bent at its inner end into one or more spirals J2, -provided with a short upright branch J 2, and terminating in a horizontal branch J4.

-To secure thestripper to the angle-iron B, I clamp a clamping-piece K, provided with the bolt-hole K', with lugs K2, adapted to project over the upper edge of the angle-iron, and with the channels K3 and K4, adapted to receive the branches J 3 and J 4, respectively, of the stripper J. A bolt L secures the clamping-piece K to the angle-iron B, and thus firmly holds in place the stripper J.

It will be obvious that the strippers may be attached in other ways, and I do not, therefore, limit myself to the specific devices shown and described; but

What I claim, and desire to secure by Letters Patent, is

In a horse hay-rake, the main frame-bar B located in front-of the axle, the strippers J of elastic metal comprising substantially the horizontal main portion J', the spire J2, the vertical portion J 2 and the horizontal portion J 4 arranged as described; and the clampingpiece K provided with the vertical channelpieces K8 and the horizontal channel-pieces K4 adapted to clamp the said strippers to the said frame-bar, substantially as described.

JAMES MACPHAIL.
